Detectives who questioned sexual predator Patrick Nevin about the rape of one woman and sexual assault of two others, all within 11 days, say he was "a grand lad to deal with".

That may have been so, but grand is not a word that could be used to describe his attitude or behaviour towards his victims, all of whom he met on Tinder.

Piggish would better describe the way he treated them. Or derogatory. Abusive. Criminal.

In each sexual attack, former UCD student Nevin used the same modus operandi. He met the women on the dating app Tinder, and after communicating with them online, he arranged to meet. He picked the women up in his car on a date and attacked them after driving them to a secluded spot.

On Tuesday, Nevin admitted before the Central Criminal Court to the rape of a woman in Bellewstown, Co Meath, on July 12, 2014.

He entered the plea at the 11th hour after a jury had been sworn in. His change of plea followed a significant legal ruling after Judge Eileen Creedon decided details of his other offences could be made known to the jury.

Nevin further admitted to sexually assaulting a woman at a location in Co Meath on July 16, 2014.

Following his guilty pleas, Nevin can be identified as the man found guilty before the Dublin Circuit Criminal Court last November of sexually assaulting a Brazilian student at UCD at Belfield on July 23, 2014.

During the trial, the woman said Nevin touched her thighs, forced her to kiss him, hit her on her head, called her a "f**king b*tch" and pulled her dress and exposed her breast.
